An article typed on a computer contains 12 pages, each page has 48 lines, each line contains 64 characters.

An article typed on a computer contains 12 pages, each page has 48 lines, each line contains 64 characters. Characters are encoded using Unicode encoding, in which each character is encoded in 16 bits. Determine the informational volume of the abstract.

The size of one character is 2 bytes. Let’s find how much information is in a line if we know that there are 64 characters in each line:
2 * 64 = 128 (bytes).
Let’s find how much information is in one page, if we know that there are 48 lines on one page:
128 * 48 = 6144 (bytes).
Let’s find how much information is contained on all 12 pages, which will be the volume of the entire abstract:
6144 * 12 = 73 728 (bytes).
ANSWER: the informational volume of the abstract is 73 728 bytes.
